Environment-friendly multistage sewage treatment device

Abstract

The invention discloses an environment-friendly multistage sewage treatment device which comprises a sewage treatment tank main body, a stirring motor is arranged at the bottom end of the sewage treatment tank main body; the bottom end of the sewage treatment tank main body is connected with a water outlet, the top end of the sewage treatment tank main body is provided with a water inlet, the topend of the stirring motor is provided with a stirring rod, the inner side of the sewage treatment tank main body is connected with a water filtering plate placing frame, and one side of the inner sideof the sewage treatment tank main body is provided with an electric telescopic rod. The device comprises a sliding block, a sliding groove, a hinge, a rotating shaft, a water filtering plate placingframe, a movable door, a connecting plate and a supporting rod; after more impurities are accumulated on the water filtering plate, the impurities on the water filtering plate can be conveniently discharged out of the sewage treatment tank in a mode of inclining the water filtering plate, so that the accumulated impurities are prevented from influencing the filtering efficiency of the water filtering plate and causing secondary pollution to sewage, and the sewage filtering efficiency of the sewage treatment device is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an environment-friendly multi-stage sewage treatment device. Background technique [0002] Sewage treatment is the process of purifying sewage so that the sewage can meet the standards of discharge to the outside water body, or can be reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment Food, catering and other fields are increasingly entering the daily life of ordinary people. At present, in the sewage treatment process, methods such as sedimentation and disinfectant disinfection are often used. [0003] At present, there are many kinds of environment-friendly sewage treatment devices on the market, but these sewage treatment devices generally have the problem that after the sewage is filtered by the water filter plate, the solid impurities acc...
